BeforeInsert, on the other hand, occurs *before* the dataset goes into
dssInsert. Therefore, at that point, the dataset is looking at the current
row in the buffer, not at a new, empty buffer row.
I suggested rewriting your handler so that it refers to the IB_Dataset
argument of the handler method. I still suggest that.
Alternatively, you could use the BeforePost event. But, when using event
handlers, be sure to refer to the method's arguments.
